Objective To investigate the effects of early partial body weight supported stand training on depression and balance function after massive cerebral infarction.Methods 40 patients with depression after massive cerebral infarction were divided into 2 groups,training group(n=20) and control group(n=20).All patients were treated with routine medication and rehabilitation.The patients of the training group also received partial body weight supported stand training in addition.They were assessed with the Hamilton depression scale(HAMD) and the Berg balance scale(BBS) before and after the treatment.Results After 8 weeks of treatment,the scores of HAMD and BBS of the training group had improved significantly more than those in the control group(P<0.05).Conclusion Early partial body weight supported stand training on the patients with depression after massive cerebral infarction may obviously improve balance function and reduce the degree of depression.

Objective To evaluate the effects of rehabilitation training according to Brtmnstrom stage on ability of daily life (ADL) and motor function of stroke patients. Methods 120 bemiplegia patients who suf-fered from stroke were randomly divided into the observation group and the control group with 60 cases in each group. Both groups received routine cerebrovascular medicine treatment and routine nursing, the observation group received rehabilitation training according to Brannstrom stage(including body position,simple kinesithera-py,daily life exercise), psychological nursing and health guidance. The motor function and ADL were as-sessed respectively by Brurmstrom assessment and Barthel index before and 4 weeks after training using rank test. Results Brurmstrom stage and ADL of the observation group were better than those of the control group after rehabilitation training. Conclusions Early rehabilitation training according to Bnmnstrom stage can obviously improve the recovery of motor function and ADL as well as life quality of stroke patients.

Objective To compare different equations for estimated glomerular filtration rate (eGFR) in patients with chronic kidney disease (CKD).Methods Hospitalized patients with CKD from the nephrology department of the First Affiliated Hospital of Nanjing Medical University (Jiangsu Province Hospital) were recruited between December 2014 and May 2015.The calculations of eGFR and 24 h creatinine clearance rate (Ccr) were accomplished in three days after admission.The eGFRs were calculated separately using the 24 h creatinine clearance rate adjusted by the standard body surface area (Ccr_BSA),Cockcroft-Gault equation adjusted by the standard body surface area (eCcr_BSA),CKD-EPI creatinine equation (EPI_Cr),CKD-EPI cystatin C equation (EPI_CysC),CKDEPI creatinine-cystatin C equation (EPI_Cr_CysC),simplified MDRD (MDRD) and China MDRD equations.The EPI_Cr_CysC equation was used as the standard and the precision and accuracy of the other six equations were compared and analyzed.Results A total of 403 CKD participants were enrolled in the study,with 228 male patients and a mean age of (54.9± 18.4) years.The main primary diseases were chronic glomerulonephritis (43.7％) and diabetic nephropathy (13.2％).The median concentration of serum creatinine and cystatin C were 117.5 (69.7,242.4) μmol/L and 1.80 (1.13,3.31) mg/L,respectively.The median values of Ccr_BSA,eCcr_BSA,MDRD,China MDRD,EPI_Cr,EPI_CysC and EPI_Cr_CysC equations were 50.8 (21.1,96.2),51.9 (23.3,93.2),53.6 (23.0,97.4),52.2(22.4,94.1),53.2 (22.1,97.3),35.1 (15.4,67.0) and 49.1 (22.8,82.3) ml · min-1 · (1.73 m2)-1,respectively.There was well agreement among MDRD,China MDRD and EPI_Cr equations,while there were large differences between equations derived from CysC (EPI_Cr_CysC and EPI_CysC) and equations derived only from creatinine (EPI_Cr,MDRD,China MDRD,eCcr_BSA,Ccr_BSA equations).Compared with EPI_Cr_CysC equation (the reference equation),EPI_Cr equation showed the highest accuracy [percentage of other eGFR equation calculations that were ＞ 30％ of the reference equation calculations (1-P30),30.8％] while Ccr_BSA equation showed the lowest (1-P30,42.4％).EPI_CysC equation showed the highest precision [inter-quartile range (IQR) of the difference,11.7 ml·min-1 · (1.73 m2)-1] while Ccr_BSA equation showed the lowest [IQR of the difference,22.8 ml· min-1 ·(1.73 m2)-1].Conclusions The agreement among equations derived only from creatinine is better;while it exhibits some differences between equations with cystatin C and equations derived only from creatinine.The accuracy of EPI_Cr equation is second only to EPI_Cr_CysC equation and it is currently the most suitable eGFR equation for clinical popularization of renal glomerular function assessment.

Objective To compare the individual effects of three recruitment maneuvers (RM) in children with congenital heart disease complicated by postoperation acute respiratory distress syndrome (ARDS).Methods A prospective single-blind randomized controlled trial was conducted.Thirty-two children with congenital heart disease complicated with ARDS after open-heart surgery undergoing mechanical ventilation were randomized into three groups,to whom three different RM was respectively performed,namely sustained inflation (SI),progressively increased positive end expiratory pressure (IP) and pressure control ventilation (PCV).Blood gas analysis was done every 6 hours,and the lung RM was performed if oxygenation index (OI) ≤ 300 mmHg (1 mmHg =0.133 kPa).The OI,the dynamic lung compliance (Cdyn),as well as the parameters of hemodynamics before,during and after RM for 15,30,and 60 minutes were recorded and analyzed before and after RM.Results During the treatment process,the OI was significantly increased during the process and 15,30 or 60 minutes after RM compared with that before RM,with no statistical difference among groups (F value was 1.027,0.403,0.264,0.172,0.159,and P value was 0.367,0.671,0.769,0.843,0.853).The Cdyn at all time points in each group was also significantly increased,but there was no statistical difference among groups (F value was 0.009,0.015,0.206,0.010,0.389,and P value was 0.991,0.985,0.814,0.990,0.683).In the process of RM,the heart rate (HR) and mean arterial pressure (MAP) of the children were lowered compared with those before RM [HR (bpm):131.67 ± 9.56 vs.138.93 ± 5.22 in SI group,133.27 ± 9.54 vs.140.33 ± 7.74 in IP group,137.13 ± 7.39 vs.142.40 ± 9.18 in PCV group,all P ＜ 0.01;MAP (mmHg):55.07 ± 4.43 vs.65.87 ± 4.46 in SI group,58.82 ± 6.04 vs.64.02 ± 7.65 in IP group,57.89 ± 4.71 vs.65.36 ± 5.37 in PCV group,all P ＜ 0.01],but it recovered immediately.CVP in all three groups was increased during RM [cmH2O (1 cmH2O =0.098 kPa):11.60±0.99 vs.5.53±0.74 in SI group,10.33± 1.35 vs.5.40±0.74 in IP group,10.20±0.94 vs.5.80±0.68 in PCV group,all P ＜ 0.01].There was significant difference in CVP during RM among three groups (F =7.327,P =0.002),and CVP in SI group was higher than that of other two groups (both P ＜ 0.05).CVP returned to the former level in 15 minutes after RM in IP and PCV groups,and recovered in 30 minutes in SI group.Conclusions All of the RM methods can effectively improve oxygenation and pulmonary compliance of the children with complication of ARDS,and they complement the inadequacy of lung protective ventilation.PCV and IP are more effective than SI in the uniform re-expansion of alveoli after RM and recovery of hemodynamics.

Sai-Luo-Tong (SLT) is a compound preparation composed of ginseng, ginkgo and saffron for the treatment of vascular dementia. In order to identify its material foundation and provide evidence for therapeutic regimen, the plasma concentration, pharmacokinetics and brain distribution of ginkgolides were investigated after intragastric ad-ministration of SLT. An LC-MS/MS method was developed for the determination of 4 ginkgolides in rat plasma and brain simultaneously. Statistical analysis of obtained data demonstrated that the method had achieved the desired lin-earity, precision, accuracy and sensitivity. The results showed that after administration of SLT at the dose of 60 mg·kg-1, 4 ginkgolides were all absorbed into systemic circulation with AUC value in the order of bilobalide B (BB) >ginkgolide A (GA) > ginkgolide B (GB) > ginkgolide C (GC). All ginkgolides exhibited short half lives less than 2.8 h among which BB showed the shortest t1/2 of 1.61 h. The determination of brain distribution at different time after dos-ing revealed ginkgolides entered into brain promptly dominated by GA and BB. The concentrations of 4 ginkgolides in brain were much lower than these in plasma and declined along with time rapidly. It was concluded that ginkgolides can be absorbed in blood and penetrated into brain rapidly. GA, BB and GB might be main components which effect both periphery and brain collectively by means of their specific mechanism to achieve the therapeutic efficacy on vascular dementia of SLT.

Objective To explore the morphological characteristics of optic tracts in healthy Chinese Han adults on the high-resolution MRI and fill the database of Chinese standard brain with morphological data of optic tracts.Methods Cerebral MRI scans with T1 WI 3D MPRAGE sequence of 1000 healthy Chinese volunteers from 15 hospitals were divided into five stages, ranging in age from 18 to 70.With the technique of multi-baseline, structure and morphology of optic tracts were displayed optimally on the images with multiplanar reconstruction.Data were measured as following: transverse distance of the cisternal optic tract (TD1) and peri-crural optic tract (TD2), length from the cisternal optic tract to the peri-crural optic tract (L) ,angle between optic tract(AOT) and height of optic tract from its first segment to plane of anterior commissure (H) including H1, H2, H3, H4 and HS.The measurements of optic tracts between sexualities and among age groups were compared by anasis of covariance; those among five age groups were compared pairwisedly by least significant difference analysis (LSD); and the differences of measurements between left and right optic tracts were analyzed using paired t test.Results (1) Comparisons of optic tract structures between male and female: the mean optic tract length of male [(11.69±1.45),(11.56±1.44) mm] was significant longer than that of female [(10.58±1.29),(10.40±1.34) mm] (F=22.236, 29.703, P=0.000); the mean H1 of male [(2.56±0.28),(2.60±0.29) mm] and female [(2.57±0.31 ), (2.63±0.32) mm] were significantly different ( F =11.130,7.805, P = 0.000, 0.005).No significant differences of the other measurements were found between male and female ( P > 0.05 ).(2) Comparisons among age groups: among 5 age groups, TD1 of both sides [left TD1 :(4.64±0.51 ), (4.64±0.57), (4.55±0.58), (4.39±0.53), (4.36±0.58)mm;right TD1 :(4.84±0.53) ,(4.80±0.60), (4.77±0.65), (4.60±0.59), (4.57±0.59) mm] and the right TD2[(3.33±0.45),(3.34±0.41),(3.33±0.36),(3.23±0.38),(3.23±0.39) mm] had statistical differences ( F = 3.458, 2.735, 4.711, P = 0.008,0.028, 0.001 ).The LSD analysis found that the 50 years old group was the watershed with significant differences ( P < 0.05 ).The results also showed that the L of both sides had statistical differences among 5 age groups ( F = 14.510,14.532, P = 0.000).The LSD analysis found that the 60 years old group was the watershed with significant differences (P <0.05).Left TD2 and the H1-H5 of both sides had no significant differences among age groups ( P >0.05).(3) Comparisons of the measurements between left and right optic tracts: TD1 of bilateral optic tracts were (4.52±0.57)and(4.72±0.60) mm respectively; H1 of bilateral optic tracts were (2.56±0.30)and (2.61±0.30) mm respectively; H2 of bilateral optic tracts were (2.66±0.30)and (2.70±0.30) mm respectively; and L of bilateral optic tracts were ( 11.14±1.47 ) and ( 10.98±1.50 )mm respectively.There were significant differences in these measurements between left and right optic tracts( t =12.460, - 6.013,5.595,4.784, P = 0.000 ), while there were no significant differences in TD2, H3, H4 and H5( P > 0.05 ).Conclusions With high-resolution MR1 and 3D reconstruction, optic tract can be displayed clearly and measured accurately.There are definite differences in anterior segments of optic tracts between sexualities, sides and among ages in normal Chinese Han adults, while the posterior segments of optic tracts keep stable.Normal reference values of optic tracts in Chinese Han adults are provided to clinical practices and scientific researches, which are valuable for building of Chinese standard brain.

Objective To explore the normal range of the fourth ventricle volume of Chinese adults of the Han nationality and provide morphological data for the construction of database for Chinese Standard Brain.Methods This is a clinical multi-center study.One thousand Chinese healthy volunteers (age range= 18 to 70) recruited from 15 hospitals were divided into 5 groups, i.e., Group A (age range = 18 to 30),B (age range =31 to 40), C (age range =41 to 50), D (age range =51 to 60), and E (age range =61 to 70).Each group contained 100 males and 100 females.All of the volunteers were scanned by MR using T1 weighted three-dimensional magnetization prepared rapid acquisition gradient echo sequence.After three dimension data reconstruction, the volumes of the fourth ventricle were measured at sagittal view by automatic trace of Midobl.2 combined with manual outlining.The difference of volumes of the fourth ventricle between male and female were analyzed by independent sample t test, and among age groups by ANOVA.Pearson's correlation coeffcient was used to characterize the relationship between volumes of the fourth ventricle and age.Results The fourth ventricle volumes of Group A-E were (2.1±0.9), (2.1±0.8), (2.2±0.8), (2.1±1.0) and (2.4±0.8) ml respectively for male; those for female were(2.0±0.7), (1.9±0.6), (18±0.6), (1.9±0.7) and (2.0±0.6) ml respectively.The fourth ventricle volumes of males were significantly larger than those of females ( t = 5.573, P =0.000 ) ; there were no significant differences among the female groups ( F = 1.788, P = 0.130 ) ; there were significant differences among the male groups ( F = 2.639, P = 0.033 ) and multiple comparison found that the 60 years old was the watershed with significant difference ( P < 0.05 ).Correlation between the change of males' volumes and the ages was not strong (r = 0.119, P = 0.008 ), and the females' volumes did not correlated with their ages ( r = 0.041,P = 0.360 ).Conclusion There are gender differences in the fourth ventricle volumes of normal Chinese adults, and changes of the fourth ventricle volume with aging are different between males and females.

Objective To investigate the effect of klotho on the human vein umbilical endothelial cells (HUVECs) injury induced by indoxyl sulfate (IS) and to explore its mechanism and the role of endoplasmic reticulum stress (ERS) in this process.Methods (1) The cell vitalities of HUVECs incubated with different concentration of IS (5,25,50 mg/L) for 48 h and with 50 mg/L IS fordifferent time points (12,24,48 h) were measured by CCK-8 assay.(2) HUVECs were incubated with 50 mg/L IS and different concentration of klotho (0,1,10,100 μg/L) for 48 h and their cell viabilities were measured by CCK-8 assay.(3) HUVECs were divided into four groups:control group,IS group (50mg/L IS),klotho group (50 mg/L IS+ 100 μg/L klotho) and Compound C group (50 mg/L IS+100 μg/L klotho+ 10 μmol/L Compound C).The cell vitality and the apoptosis of HUVECs were evaluated by CCK-8 assay and flow cytometry,respectively.The mRNA and protein expressions of GRP78 and CHOP were measured by real-time PCR and Western blotting.The phosphorylation level of AMPK was tested by Western blotting.Results IS inhibited cell vitality in the time-dependent and concentration-dependent manner.The cell viability of HUVECs with 50 mg/L IS was lower than normal control (P＜0.05).The inhibited cell vitality induced by IS was partly restored by klotho in concentration-dependent manner.The cell viability was higher in 100 μg/L klotho+50 mg/L IS group than 50 mg/L IS group (P ＜ 0.05).Compared with control group,the expressions of GRP78 and CHOP and cell apoptosis increased,however,the level of phosphorylated AMPK (p-AMPK) decreased in IS group (all P ＜ 0.05).Compared with IS group,the expressions of GRP78 and CHOP and cell apoptosis decreased and the level of p-AMPK increased in klotho group (all P ＜ 0.05).Furthermore,the above effects of klotho could be partly blocked by Compound C.The above indexes showed statistical differences between Compound C group and klotho group.Conclusions IS can inhibit the HUVECs cell vitality,and induce ERS and cell apoptosis.Klotho protein could antagonize the above effects,probably through activating AMPK pathway and reducing ERS-mediated cell apoptosis.

Objective To understand the infection status of enterovirus 71(EV71) and coxsackievirus A16(Cox A16) among children receiving health examination for child care setting entrance in Beijing and their related medical care seeking practice and provide evidence for the estimation of disease burden caused by hand foot and mouth disease(HFMD). Methods Serological survey was conducted in the local children receiving health examination for child care setting entrance. Enzyme-linked immunosorbent assay (ELISA) was conducted to detect anti-EV71 and anti-Cox A16 IgG and IgM. Results A total of 813 children were surveyed(mean age:3.5±1.0 year old). The seropositive rate was 61.9%and 4.4%for anti-Cox A16 IgG and IgM. The seropositive rate was 9.3% and 1.1% for anti-EV71 IgG and IgM. No significant difference was observed in sex specific seropositive rate (P>0.05). However,significant differences were found in seropositive rate among different age groups(P<0.05). Among the children who were anti-Cox A16 positive, 7.8%had ever had rashes on their hands and feet,mouth or buttocks(HFMD-like rashes). Among the children who were anti-EV71 positive,10.7%had ever had HFMD-like rashes. For the children who were anti-Cox A16 or anti-EV71 positive,only 7.1% were brought to see doctors by their parents. However,among the seropositive children with rashes,80.5% were brought to see doctors. Conclusion In the healthy children at the age to go to child care setting in Beijing,most had ever infected with Cox A16. The anti-EV71 positive rate was much lower than the anti-Cox A16 positive rate. It was necessary to strengthen the prevention and control of EV71 infection in child cares settings.

Objective:To analyze the changes of diagnosis and treatment before and after renal biopsy in adult patients with acute kidney disease (AKD), and to explore the value of renal biopsy in the diagnosis and treatment of AKD.Methods:It was a single-center retrospective observational study. The adult patients with AKD who underwent renal biopsy in the Department of Nephrology of the First Affiliated Hospital of Nanjing Medical University from January 1, 2017 to December 31, 2021 were enrolled. Demographic data, general clinical data, laboratory tests, and diagnosis and treatment data before and after renal biopsy were collected to analyze the concordance rate between clinical and pathological diagnoses, changes in treatment after renal biopsy, and bleeding complication.Results:A total of 575 patients diagnosed with AKD by renal biopsy were included in this study, with age of 51 (36, 63) years old and 359 males (62.4%). Among them, there were 293 patients (51.0%) of acute kidney injury, 348 patients (60.5%) of hypertension and 124 patients (21.6%) of diabetes. The peak serum creatinine was 272 (190, 477) μmol/L. The hemoglobin was 106 (86, 126) g/L. The 24-hour urine protein was 2.15 (0.79, 4.82) g. There were 347 patients (60.3%) of acute glomerular diseases, 136 patients (23.7%) of acute interstitial nephritis, 47 patients (8.2%) of thrombotic microangiopathy, and 45 patients (7.8%) of acute tubular necrosis. The most common types of acute glomerular diseases were IgA nephropathy and anti-neutrophil cytoplasmic antibody-associated glomerulonephritis, accounting for 22.3% (128/575) and 12.2% (70/575), respectively. The clinical diagnoses before renal biopsy were consistent with the renal histopathological diagnoses in 454 patients, with an accuracy rate of 79.0%. Following the renal biopsy, the treatment plan involving glucocorticoids or immunosuppressants was adjusted in 394 patients (68.5%). Significant post-biopsy bleeding occurred in 15 patients (2.6%), with 12 patients requiring blood transfusion and 1 patient requiring surgical intervention.Conclusions:Twenty-one clinical diagnoses do not match the pathological diagnoses in adult AKD patients, 68.5% of patients have changes in their treatment plans, and 2.6% of patients have significant hemorrhagic complications after renal biopsy. Clinicians need to carefully consider the benefits and risks and make individualized decisions about renal biopsy.
